I read the instructions on a bear spray container for sale at Walmart. It said that the spray “can” be effective as a bear deterrent. When in bear country, if you carry a handgun it’s best to have one with a 4 somewhere in the caliber.
Anyone want to venture a guess where the bears hide ended up?
The “4” may not be as important as you think:
